I don't know why but Nepal counts cities in a really strange way. I visited Pokhara and the city is much bigger than 260k inhabitants. There are probably like 1,5 million people in the city proper and 3 million people in the metro area. The city was very big and very densely populated so there is no way that there are only 260k inhabitants. Especially compared to the Dutch city were I live since there are much less people per square km compared to Pokhara.
